Add users to a group chat
You can add participants to a group chat, either from your frontend or from your backend using the REST API. You can't directly add guest users to a group chat, as guests aren't members of a conversation. You can, however enable or turn off guest access.
Users can join a group chat at any time during the lifetime of a conversation. Joining a chat works differently for participants and guests, in the following way.
You can programmatically add participants to a group chat either from your frontend or from your backend, as follows.
To add a participant to a conversation from your frontend, use ParticipantRef from the JavaScript Data API or JavaScript Chat SDK.
To add a participant to a conversation from your backend, call the Join conversation endpoint of our REST API.
You can't add guests to a conversation in the same way as you can add participants. Instead, you can set things up so that users who aren't participants in a conversation can access that conversation as a guest.
To allow a user to join a conversation as a guest, enable guest access and make a chat interface with that conversation available to the user. Any user who knows the conversation’s ID and is not already a participant in that conversation, can now access this conversation as a guest.
